Ductwork services
Installation, repair, sealing & evaluating — all covered
Your ductwork is the delivery system for every dollar you spend on heating and cooling. Leaky, or damaged, ducts waste energy, create uneven comfort, and reduce air quality. We handle every aspect of ductwork for homes and businesses across Southern Maryland, Anne Arundel County, and Southern Prince George's County.
Duct installation
New ductwork designed and installed for new construction or full system replacements. We engineer for optimal airflow, balanced pressure, and long-term efficiency using quality materials built to last.
Duct repair
Damaged, disconnected, or deteriorating ducts cause uneven heating and cooling and drive up energy costs. We locate and repair all types of duct damage — from minor tears to collapsed sections.
Duct sealing
Leaky duct joints and connections allow conditioned air to escape into attics, crawlspaces, and wall cavities — air you've already paid to heat or cool. Professional duct sealing stops the waste at the source and can significantly reduce monthly energy bills.
Warning signs
Signs your indoor air quality may need attention
Most homeowners don't realize their ductwork is the problem. These are the most common signs we see that point to duct issues.
Rooms that won't heat or cool
Hot or cold spots in specific rooms often point to disconnected ducts, blockages, or poor duct design for that area of the home.
Unexpectedly high energy bills
A sudden or gradual rise in heating and cooling costs without explanation is one of the clearest signs of leaky or damaged ductwork wasting conditioned air.
Weak airflow from vents
Low or inconsistent airflow from registers is often caused by leaks, blockages, or collapsed sections preventing air from reaching the room.
Excessive dust throughout the home
Leaky ducts in dusty areas like attics and crawlspaces pull in unfiltered air and debris, circulating it through every room.
Musty or stale odors from vents
Musty smells coming through vents can indicate mold or mildew growth inside the ductwork — a problem that spreads contaminants throughout the home every time the system runs.
Rattling or banging from ductwork
Unusual sounds when the system starts or runs often indicate loose duct sections, poor connections, or expanding metal from pressure imbalances.
System runs constantly but doesn't keep up
When an HVAC system runs for long periods without reaching the set temperature, leaky ducts are often losing too much conditioned air before it reaches the living space.
Ductwork is old or was never inspected
Ductwork in homes over 15–20 years old is likely using materials that have degraded over time and may never have been professionally inspected or cleaned.
ENERGY SAVINGS
Leaky ducts are costing you money every month
Most homeowners don't realize how much energy their ductwork is wasting. Here's what the research shows — and what we can do about it.
20–30%
of conditioned air lost through
leaky ducts, per the U.S. DOE
Professional duct sealing pays for itself
The U.S. Department of Energy estimates that leaky ductwork causes homes to lose 20–30% of their heated and cooled air before it ever reaches the living space. That's energy you've already paid for — escaping into attics, crawlspaces, and wall cavities.

Common questions
HVAC ductwork FAQs
Answers to the questions we hear most from homeowners and businesses across Southern Maryland.
How do I know if my ducts are leaking?
Common signs of leaky ductwork include rooms that are consistently harder to heat or cool than others, higher-than-expected energy bills, excessive dust buildup on surfaces, weak airflow from certain vents, and a system that runs constantly without reaching the set temperature. A professional ductwork inspection can confirm leaks and identify exactly where they're occurring.
How long does HVAC ductwork last?
Well-installed sheet metal ductwork can last 25 years or more with proper maintenance. Flexible duct typically lasts 10–15 years before showing signs of degradation. Older homes with original ductwork — especially those using fiberglass duct board or older flexible materials — are prime candidates for inspection and possible replacement.
What is duct sealing and how is it different from duct repair?
Duct repair addresses physical damage — collapsed sections, disconnected joints, or torn flexible duct. Duct sealing focuses on closing small gaps, cracks, and leaks at joints and connections that allow conditioned air to escape. Both are often needed together. Professional sealing uses mastic sealant or metal-backed tape applied to all connection points — not the household duct tape which degrades quickly.
Can you add ductwork for a home addition or newly finished room?
Yes. We extend existing duct systems to serve new additions, finished basements, bonus rooms, and converted spaces. We assess your current system's capacity first to ensure it can handle the additional load — if not, we'll discuss options including supplemental mini split systems for the new space.
Do you service commercial ductwork?
Yes. We provide ductwork installation, repair, sealing, and cleaning for commercial properties throughout Southern Maryland, Anne Arundel County, and Southern Prince George's County — including offices, retail spaces, warehouses, and multi-unit buildings.
How long does a ductwork inspection take?
A thorough ductwork inspection typically takes 1–2 hours for a standard residential home. We assess all accessible duct sections, check for leaks and damage, evaluate airflow balance, and review the condition of connections and insulation. You'll receive a clear summary of findings and recommendations before any work is proposed.
